I just stumbled on a site called celsias that has a section called Actions that’s all about people making small but important changes in their lives. There is a social aspect to this, each change appears in a list that shows how many people are pledging to do it and how many people want to do it. Members and tasks have some kind of system of degrees that I don’t understand.

As of today, 39 celsias members are not using plastic bags. That’s a good start :)
